A concentrated force, F is applied (perpendicular to the plane of the figure) on the tip of the bent bar shown in Figure. The equivalent load at a section close to the fixed end is:
Two identical cantilever beams are supported as shown, with their free ends in contact through a rigid roller. After the load P is applied, the free ends will have
As it is rigid roller, deflection must be same, because after deflection they also will be in contact. But slope unequal.
A mass less beam has a loading pattern as shown in the figure. The beam is of rectangular cross -section with a width of 30 mm and height of 100 mm.

What is the maximum shear force in the beam?
A lever is supported on two hinges at A and C. It carries a force of 3 kN as shown in the above figure. The bending moment at B will be
The bending moment (M) is constant over a length segment (I) of a beam. The shearing force will also be constant over this length and is given by
The bending moment is constant over a length of a segment of a beam. The shearing force will also be a constant over this length by M/l
Consider the following statements:
If at a section distant from one of the ends of the beam, M represents the bending moment. V the shear force and w the intensity of loading, then
1. dM/dx = V
2. dV/dx = w

Select the correct answer using the codes given below:
If the shear force acting at every section of a beam is of the same magnitude and of the same direction then it represents a
The shearing force diagram for a beam is shown in the above figure. The bending moment diagram is represented by which one of the following?
Uniformly distributed load on cantilever beam.
A vertical hanging bar of length L and weighing w N/ unit length carries a load W at the bottom. The tensile force in the bar at a distance Y from the support will be given by
Assertion (A): If the bending moment along the length of a beam is constant, then the beam cross section will not experience any shear stress.
Reason (R): The shear force acting on the beam will be zero everywhere along the length.
What is the bending moment at end supports of a simply supported beam?
At the end supports, the moment (couple) developed is zero, because there is no distance to take the perpendicular acting load. As the distance is zero, the moment is obviously zero.
If a beam is subjected to a constant bending moment along its length, then the shear force will
